Paul Pogba may be struggling at Manchester United this season because of his success with France at the World Cup, Frank Leboeuf claims.

The United midfielder has struggled for form this season having impressed for France in Russia over the summer.

And Leboeuf, who won the trophy with France in 1998, admitted he experienced similar problems when he returned to Chelsea having won the biggest prize in football.

"It was very hard to come back to Chelsea, to the training ground, to start running, to think we had to play the first game away to Coventry," the former Chelsea defender told ESPN.

“As Paul said, you touch the stars. For thousands of people it wasn’t a dream, it was a fantasy. Suddenly you win it and you have to find the goals to make sure you still have a big appetite in football.
